Fig. 4 is to illustrate the schematic sectional view of the movement of display device of the 1st embodiment.
Fig. 4 instantiates the 2nd movement ST2.
In the 2nd movement ST2, the 1st transmissivity Ta1, the 3rd transmissivity Ta3 and the 5th transmissivity Ta5 are respectively than the 2nd transmissivity Ta2, the 4th transmissivity Ta4 and the 6th transmissivity Ta6 are low.In the 2nd movement ST2, the 1st intermediate transmission rate Tb1, the 3rd intermediate transmission Rate Tb3 and the 5th intermediate transmission rate Tb5 are respectively than the 2nd intermediate transmission rate Tb2, the 4th intermediate transmission rate Tb4 and the 6th intermediate transmission rate Tb6 is low.
In the 2nd movement ST2, position corresponding with the 1st electrode e1, the 3rd electrode e3 and the 5th electrode e5 is non-transmissive respectively State.Position corresponding with the 2nd electrode e2, the 4th electrode e4 and the 6th electrode e6 is light transmission state respectively.

For example, the light (such as light comprising right eye image) of the 1st parallax projected from display unit 210 is entered with the 3rd angle It is mapped to switching Liquid Crystal portion 110.The light is for example incident on and some corresponding part with the 2nd pair, the 4th pair and the 6th pair The right eye 81 of viewer 80.The light (such as light comprising left eye image) of 2nd parallax is incident on switching Liquid Crystal portion 110.The light Such as sight is substantially not incident in some corresponding part decaying (such as blocking) with the 1st pair, the 3rd pair and the 5th pair The right eye 81 of the person of seeing 80.
On the other hand, the light L1 (such as light comprising left eye image) of the 2nd parallax projected from display unit 210 is with the 4th Angle is incident on switching Liquid Crystal portion 110.The light is for example and some corresponding part with the 2nd pair, the 4th pair and the 6th pair It is incident on the left eye 82 of viewer 80.The light (such as light comprising right eye image) of 1st parallax is incident on switching Liquid Crystal portion 110.The light is for example substantial not in some corresponding part decaying (such as blocking) with the 1st pair, the 3rd pair and the 5th pair It is incident on the left eye 82 of viewer 80.
During the 2nd, the position of viewer 80 is 2nd position different from the 1st position.In the 2nd movement ST2, example It such as can be to the incident light different from each other of right eye 81 and left eye 82 of the viewer 80 of the 2nd position.By using including multiple views The light L1 of difference implements such as 3 dimension displays.
Like this, control unit 70 also implements the 2nd movement ST2 during the different from during the 1st the 2nd.2nd movement ST2 It include: to make the 2nd transmissivity Ta2 and the 2nd intermediate transmission rate Tb2 respectively than the 1st transmissivity Ta1 and the 1st intermediate transmission rate Tb1 high.
For example, the head of viewer 80 is mobile.Alternatively, the angle of such as switching Liquid Crystal portion 110 (or display device 310) becomes More.Space configuration variation between switching Liquid Crystal portion 110 and viewer 80.
Control unit 70 obtains and the related information of space configuration between viewer 80 and switching Liquid Crystal portion 110.For example, control Implement the 1st movement ST1 when being configured to the 1st state (the 1st position) based on acquired information, be configured to and the 1st in portion 70 processed Implement the 2nd movement ST2 when different the 2nd state (the 2nd position) of state.
By the 1st movement ST1 and the 2nd movement ST2, it is able to carry out and follows between viewer 80 and switching Liquid Crystal portion 110 The tracking of the variation of space configuration acts.
In addition, in Fig. 3, Fig. 4,2 continuous electrodes are right as 1, but 1 pair of number of electrodes is not limited to 2, only If continuous at least one electrode in the X-axis direction.
In embodiments, when projecting to the 1st face 10a, multiple lateral electrodes 12 and multiple medial electrodes 11 can be mutual Overlapping, can not also be overlapped.When projecting to the 1st face 10a, multiple lateral electrodes 12 and the overlapped feelings of multiple medial electrodes 11 Under condition, the capacity coupled influence between medial electrode 11 and lateral electrode 12 becomes larger, and supplies from control unit 70 to these electrodes Signal generate distortion, image quality may decline.
It in this case, in embodiments, can be using multiple lateral electrodes 12 and multiple when projecting to the 1st face 10a The construction that medial electrode 11 does not overlap each other.Thereby, it is possible to inhibit capacitive coupling, implements desired movement, high image quality is provided Display device.
On the other hand, such as shown in figure 12, in the case where medial electrode 11 being arranged and be not provided with lateral electrode 12, Multiple medial electrodes 11 generate the indeclinable region of transmissivity each other.Thus, for example contrast declines.Or under brightness Drop.
In turn, medial electrode 11 also can be set and is not provided with lateral electrode 12, between multiple medial electrode 11 Light shield layer is set.In this case, brightness declines.
In contrast, in the switching Liquid Crystal portion 110 of embodiment, multiple medial electrodes 11 and multiple outer are alternately arranged Lateral electrode 12.Crosstalk is reduced thereby, it is possible to reduce light leakage.
In embodiments, it 1 in multiple medial electrodes 11 when preferably projecting to the 1st face 10a and is adjacent The distance between lateral electrode 12 it is short.For example, when projecting to the 1st face 10a, preferably the 1st electrode e1 and the 1st target f1 Between the 1st direction (such as X-direction) distance (gap) be the 1st electrode e1 the 1st direction width 1/10 or less.By This, the gap between medial electrode 11 and lateral electrode 12 substantially disappears, and does not generate the indeclinable region of transmissivity substantially. In addition, having the tendency that the end extended in electrode from the electric field that the end of electrode is extended.Therefore, if the 1st electrode e1 and the 1st The distance between target f1 (gap) is the 1/10 of the width of the 1st electrode e1 hereinafter, then the influence in gap substantially can be with Ignore.
For example, more preferably, the 1st direction when projecting to the 1st face 10a, between the 1st electrode e1 and the 1st target f1 Distance be the 1st electrode e1 the 1st direction width 1/20 or less.
1st movement ST1 include: so that between the 1st electrode e1 and opposite electrode 21 current potential absolute value of the difference (the 1st absolutely Value) and the 1st target f1 and opposite electrode 21 between current potential absolute value of the difference (the 1st intermediate absolute value), respectively than the Current potential absolute value of the difference (the 2nd absolute value) and the 2nd target f2 and opposed electricity between 2 electrode e2 and opposite electrode 21 Current potential absolute value of the difference (the 2nd intermediate absolute value) between pole 21 is big.For example, when being benchmark with opposite electrode 21, it is dynamic the 1st Make in ST1, the voltage applied to the 1st electrode e1 of light transmission state and the 1st target f1 is than the 2nd electricity to non-transmissive state The voltage that pole e2 and the 2nd target f2 applies is high.Implement the movement often closed.
In the case where implementing the movement often closed, the 2nd movement ST2 includes: so that the 2nd absolute value and the 2nd intermediate absolute value point 1 absolute value of Bie Bi and the 1st intermediate absolute value are big.
On the other hand, the 1st movement ST1 includes: the current potential absolute value of the difference so that between the 1st electrode e1 and opposite electrode 21 Current potential absolute value of the difference (the 1st intermediate absolute value) between (the 1st absolute value) and the 1st target f1 and opposite electrode 21, Respectively than the current potential absolute value of the difference (the 2nd absolute value) and the 2nd target f2 between the 2nd electrode e2 and opposite electrode 21 Current potential absolute value of the difference (the 2nd intermediate absolute value) between opposite electrode 21 is small.For example, when being benchmark with opposite electrode 21, In the 1st movement ST1, to the voltage ratio that the 1st electrode e1 of light transmission state and the 1st target f1 apply to non-transmissive shape The voltage that 2nd electrode e2 of state and the 2nd target f2 applies is low.Implement normally opened movement.
In the case where implementing normally opened movement, the 2nd movement ST2 includes: so that the 2nd absolute value and the 2nd intermediate absolute value point 1 absolute value of Bie Bi and the 1st intermediate absolute value are small.
Often pass and the polarization axle of the normally opened polarization axle that can for example pass through the 1st polarization layer 51 of change and the 2nd polarization layer 52 Relationship changes.By the dielectric anisotropy of liquid crystal used in liquid crystal layer 30, the pass of voltage and transmissivity can be changed System.
Fig. 5 is the schematic sectional view of a part of the display device of the 1st embodiment of example.
Fig. 5 shows another example of the 1st baseplate part 10u.
As shown in figure 5, in switching Liquid Crystal portion 111, the width of respective 1st direction (X-direction) of multiple medial electrodes 11 It spends bigger than the width in respective 1st direction of multiple lateral electrodes 12.
Insulating layer 15 is not provided between medial electrode 11 and liquid crystal layer 30.In contrast, in outer lateral electrode 12 and liquid crystal Insulating layer 15 is provided between layer 30.In the voltage applied between outside lateral electrode 12 and opposite electrode 21, pass through insulating layer 15 and generate voltage decline.If potential difference (voltage) between medial electrode 11 and opposite electrode 21 and lateral electrode 12 and right The potential difference (voltage) set between electrode 21 is identical, then in that region, it is poor that the voltage actually applied to liquid crystal layer 30 generates It is different.In and the corresponding region of medial electrode 11 and region corresponding with lateral electrode 12, the difference of transmissivity is generated sometimes.
In this case, in switching Liquid Crystal portion 111, keep the width of medial electrode 11 bigger than the width of lateral electrode 12. The actual effect area of medial electrode 11 becomes larger as a result, so the influence of medial electrode 11 is bigger than the influence of lateral electrode 12.As a result, Even if generating transmissivity in and the corresponding region of medial electrode 11 and region corresponding with lateral electrode 12 since voltage declines Difference, as a whole also equably implement switching Liquid Crystal movement, speck can be further suppressed.Therefore, crosstalk can be reduced, Implement the higher display of image quality.
For example, the width in respective 1st direction of multiple medial electrodes 11 is respective 1st direction of multiple lateral electrodes 12 1.1 times or more 10 times or less of width.Alternatively, the width in respective 1st direction of multiple medial electrodes 11 is also possible to outside multiple 1.2 times or more 5 times or less of the width in respective 1st direction of lateral electrode 12.In such range, by making medial electrode 11 Width it is bigger than the width of lateral electrode 12, higher image quality can be obtained.If the width of medial electrode 11 and outside electricity The ratio between the width of pole 12 is excessively high, then the width of lateral electrode 12 is meticulous, and resistance is got higher.
As described above, in the voltage applied between outside lateral electrode 12 and opposite electrode 21, pass through insulating layer 15 Generate voltage decline.In order to be compensated to it, the voltage of the internal supply of lateral electrode 11 can be made and lateral electrode 12 is supplied Voltage it is different.
For example, in the 1st movement ST1, making among the corresponding with the 1st target f1 the 1st absolutely in the movement often closed It is worth bigger than the 1st absolute value corresponding with the 1st electrode e1.The 2nd movement ST2 in, make in the 2nd target f2 the corresponding 2nd Between absolute value ratio the 2nd absolute value corresponding with the 2nd electrode e2 it is big.The influence of voltage decline is compensated.
For example, in the 1st movement ST1, making among the corresponding with the 2nd target f2 the 2nd absolutely in normally opened movement It is worth bigger than the 2nd absolute value corresponding with the 2nd electrode e2.The 2nd movement ST2 in, make in the 1st target f1 the corresponding 1st Between absolute value ratio the 1st absolute value corresponding with the 1st electrode e1 it is big.The influence of voltage decline is compensated.
